Abstract: Transfer learning for a target domain that partially matches classification of a source domain having a ground truth is enabled. A learning device stores a first set subjected to classification and assigned with a ground truth and a second set having a class that partially matches the first set, and executes, based on a first loss function of first data and a second loss function of second data, processing of updating, by the number of updates, an identifier for identifying the first data and the second data when a feature of the first data or a feature of the second data is input. The learning device calculates a similarity at which the first data is similar to the second data by a data selector that calculates the similarity at the last time, and updates the data selector and the first distribution based on the estimated value.

Abstract: This invention is directed to a method of efficiently improving a relative density of a shaped object using an evaluation criterion having a higher correlation with a density of an object to be shaped. The method according to this invention includes acquiring three-dimensional point group data of a surface of a shaping object, calculating at least one of three-dimensional surface texture parameters extended to a plane region using the three-dimensional point group data, and evaluating a quality of the object to be shaped using the at least one of the three-dimensional surface texture parameters.

Abstract: A calculation device used in a manufacturing apparatus for producing a 3D manufactured object from a solidified layer formed by heating a layer-shaped material layer formed of a powder material by irradiation with an energy beam includes a detection unit configured to obtain a state of the material layer based on a shape of the formed material layer, and an output unit configured to output information on the state of the material layer obtained by the detection unit to set a manufacturing condition of the manufacturing apparatus.

Abstract: A calculation device used in a manufacturing apparatus for producing a 3D manufactured object from a solidified layer formed by heating a powder material by irradiation with an energy beam, includes a detection unit configured to obtain a state of at least a part of a predetermined region including a melted portion in which the powder material melts by being heated by irradiation with an energy beam, and an output unit configured to output state information based on the state obtained by the detection unit to change a manufacturing condition of the manufacturing apparatus.
